orca

Orca runs a fleet of coding agents side by side so you can pick the winner. Point it at a task and it spins up several agents (Claude Code, Codex, OpenCode, whatever you already use), each working in its own isolated git worktree, then you compare the diffs and merge the one that got it right. It is a desktop app for macOS, Windows, and Linux, MIT licensed, and free.

Running it is a download. Point it at CLI agents you already have and it handles the worktree juggling, terminal splits, a built-in browser, GitHub and Linear integration, and a tracker for Claude and Codex usage limits. Your real cost is the agent subscriptions: Orca drives tools you already pay for and never sits between you and the model. A mobile companion kicks off runs from your phone.

For a solo developer who runs one agent at a time, this is a workflow upgrade the day you install it, and it costs nothing. Small teams get the same benefit per person. Larger teams can run an always-on Orca server inside their own network, and Orca Enterprise is available by contact with no published price.

The catch is that parallel agents multiply your token spend fast. Running five agents on the same task means paying for five attempts to keep one. That math works when the task is hard and wasteful when a single agent would have nailed it. Deciding when the fleet is worth it is on you.
